Order #719346 - Hglrc Draknight 2-Inch Toothpick Fpv Drone (Elrs) - VTX Issues - VTX not responding to betaflight and outputting to the wrong channel

Order Number: 719346
Product Name: Hglrc Draknight 2-Inch Toothpick Fpv Drone (Elrs)
Brand: HGLRC
My draknight was flying fine yesterday, I only flew 2 packs and I didn’t have any crashes or anything yesterday. I go to fly it today and the video isnt trasmitting to the goggles. I searched the channels with my goggles and found it is outputting on A2/3 instead of R8 which is what I usually use. The range is terrible on A2/3 but it is the only channel I am getting video to. I have tried resetting the drone in betaflight and installing a new antenna but the issue is still the same. i have reset the drone and used the cli dump file to try and get it back to factory settings, even though the only things I configured was the rates and osd when I first got it. I have only flown it for about 10 packs and it’s only started doing this today. It’s had a few small crashes into grass on the garden but it has always carried on flying fine. Just wondering if you have ever seen anything like this? Is my aio dead?
I have tried resetting the drone in betaflight, and then flashing with a CLI dump, then I installed a new antenna but the issue is still the same.
I have been sent the vtx table from HGLRC and I have flashed that with betaflight and t he issue is still the same.

Thank you for reaching out to us and for providing such a detailed description of the issue with your HGLRC Draknight drone (Order # 719346), along with all the troubleshooting steps you’ve already taken. We understand how frustrating it must be for the VTX to suddenly stop working correctly, especially when you haven’t had any major crashes.

You’ve done an excellent job troubleshooting this. Resetting Betaflight, applying the CLI dump, flashing the official VTX table from HGLRC, and even trying a new antenna covers all the usual software and basic hardware fixes we would typically suggest.

Given that the problem (transmitting on the wrong channel A2/3 with very poor range, instead of R8) persists despite all these steps, it strongly suggests that the issue is likely not a simple configuration error but rather points towards a potential hardware fault within the video transmitter (VTX) section of the All-In-One (AIO) board. This could potentially be an issue with the VTX’s power amplifier (explaining the poor range) or its control circuitry (explaining the incorrect channel). While unfortunate, hardware components can sometimes fail unexpectedly even without severe impacts.

Our Next Step:

We have compiled the information you provided and have contacted HGLRC support directly on your behalf. We’ve detailed the symptoms and the extensive troubleshooting you’ve performed, and asked for their technical advice, suggestions for any further diagnostics, or guidance on how to proceed under warranty if they also suspect a hardware failure.

What Happens Now:

We will need to wait for a response from HGLRC. They may have further specific checks they’d like performed, or they may provide instructions for a warranty claim or replacement based on the information.

We will keep you updated as soon as we hear back from them. Please know that we’ll do our best to help facilitate a resolution for you.

Thanks again for your patience and detailed report.

Kind Regards

Hi

It seems that HLGRC are not accepting that this is due to a manufacturing defect and suggesting that something like wet grass could of damaged the VTX. However they are offering a 50% discount on a replacement AIO for this drone. We can then cover the other half ourself as a gesture of goodwill. If you wish to do this, please let me know so I can get this sorted out of you (we do not have stock of the FC at the moment)

Kind Regards

Okay no problem that would be perfect. I do not mind paying for the aio but I really appreciate it for covering that cost. Thank you for sorting this out for me.

Hi Kirk good day,

I’m glad we could assist with this, HGLRC were really nice to offer the 50% refund even though it was not faulty.

Not a lot of companies would offer this to be honest.
